What really happened in Iran during that election count? As thousands protest against the results and demonstrate, we've gone to the Iranian Ministry of the Interior to get the official version of events.

We've then got the Presidential Office's eligible voters by region data so we can work out what the turnout as in each case. Whether you believe over 99% turnouts anywhere is one thing, but this data is only the beginning. In some places you can see that the number of people voting is actually higher than the number of eligible voters - as admitted by the Guardian Council.

There are other versions of this stuff out there - Fivethirtyeight.com has visualised these figures as a map, while Iran Tracker has another set. The figures we've uploaded are, as far as we can work out, the official totals, so you should be safe using them. We've also added on the 2005 results on the spreadsheet - just click on the link.

This shows the percentage of the vote polled by Mahmoud Ahmadinejad across Iranian provinces in the first round of the 2005 (blue) and 2009 (orange) presidential elections. The combined conservative candidates (red) are Ahmadinejad, Ali Larijani and Mohammad Baqer Qalibaf. Ahmadinejad and the reformist Ali Akbar Hashemi Rafsanjani went head-to-head in the second round.
